Specification of Letters Patent.

Patented June 29, 1915.

Application filed January 10, 1914. Serial No. 811,382.

To all whom it may concern Be it known that I, FERDINAND E. KAUFF- MANN, a citizen of the United States, and a resident of Rahway, county of Union, and State of New Jersey, have invented certaln new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to any improved horseshoe in which the horseshoe proper 1s not subjected to appreciable wear, belng adapted to be removed from the horses hoof only to permit paring of the hoof, the shoe being adapted to be replaced on the hoof, and being provided with a bottom plate or bottom plates. The bottom plates can be wearing plates, they can be provided with calks, or they can have other non-sllpplng devices, the bottom plates belng adapted to be secured to the shoe without the servlces of a blacksmith being necessary, these plates not being removed by accident or wear, but being removable by design, which removal, however, would be only necessary under unusual circumstances. The bottom plate s made of malleable material and is applied 1n distorted form, that is, it is bent out of the shape it assumes when in place on the shoe, the plate and the shoe havlng co-actlng means which are adapted to interlock and hold the plate firmly on the shoe when the plate is hammered or otherwise positively forced against the shoe so that it is no longer distorted.

The invention is susceptible to modification, and in order to illustrate the invention, I have shown several embodiments of the 1nvention in the accompanying drawlngs, 1n which- Figure 1 is a perspective view of a horseshoe and a wearing plate which is adapted to fit against the bottom of the shoe, the shoe and the plate both being illustrated 1n perspective and slightly separated, the plate being in its distorted form. Fig. 2 1s a side view of a horseshoe and a plate, such as shown in Fig. 1, but with the plate attached to the shoe and forced from its distorted position, the interlocking portion of the shoe and the plate being broken away to show them in section. Fig. 3 is a top view, and Fig. 4; is a bottom view of a modified form of plate, and Fig. 5 is a section on line 5-5 in Fig. 3, showing a modified form of calks, and a form of finger difierent from that illustrated in Figs. 1 and 2.

The horseshoe 10 is, in the main, constructed as the usual form of horseshoe, being fitted to the margin of the hoof, and adapted to be fastened therein in any convenient manner, this being usually done by horseshoe nails driven through the nail holes 11. The wearing plate 12, which is a bottom plate fitting against the bottom of the shoe, is adapted to be interlocked or positively secured to the horseshoe by co-acting means on the shoe and on the plate, these means being of diflerent types, one form being illustrated, however, in Figs. 1 and 2. In this form the horseshoe is provided with recesses 13 which have their outer walls, that is, the wall of each recess on the side opposite the other recess on that side of the shoe, formed with an inclined face 14, this being done since the plates are usually supplied to the shoe in pairs, one to be fastened on the outside edge, and the other to be fastened on the inside of the shoe and approaching each other as closely as desired toward the front of the shoe. The wearing plate 12 is of malleable material, usually malleable iron, and is provided with fingers 15, which project from the plate on its top surface, and are so arranged that when the plate is dis torted, as shown in Fig. 1 and in dotted outline in Fig. 2, the ends of the projections 15 will enter the recesses 13. WVhen in this position the shoe acts as an anvil or backing for the plate, and if the plate is forced from its distorted position by hammering or other means, the plate is straightened out, the fingers are spread from each other, and they enter farther into the recesses 13 and are interlocked therein by having the fingers bear tightly against the inclined walls 14 of the recesses. This interlocking position is clearly illustrated in Fig. 2.

To facilitate the bending of the plate, it is provided with a weakened portion or portions, the drawing showing one portion, which is formed by providing the top face of the plate with a groove 16. This groove has other functions, one of them being to provide a place for the insertion of a tool, if necessary, to distort the plate to withdraw it from the shoe, the second being that when the plate is worn down so thin that it wears through the thinned portion 17 opposite the groove, the plate will be worn so that it divides into two pieces, and the two pieces can be easily removed, or they drop out by themselves, from the shoe, and a new plate is easily secured in the recesses lately vacated by the worn bottom plate. The bottom plates 12 can be made in any desired form and with any suitable wearing surface, the form shown in Figs. 1 and 2 having calks 18, in this form the calks and the projections 15 being integral with the plate, and being struck up therefrom so as to form a cheap structure, although they may be made in different forms a d different manners.

In the form of plate shown in Figs. 3 and 4, I illustrate heavier calks 19, which are particularly adapted for winter wear and are provided with lateral or branch calks 19*. In this formof calk the shoe is made of malleable material which is preferably cast around the calk, the calk being placed in the mold and the metal being poured around the calk so as to firmly embed it. A large section is shown in Fig. 5 to more clearly illustrate this, the material of the plate 12 firmly securing the calk 19 and its arm 19 by being molded over and around it, the calk being integral with the finger 20. This form of finger is drawn to illustrate a modification, the finger, at its base, being substantially straight, and perpendicular to the upper face of the plate, as at 21, the straight or neck portion being inclined with a tapering nose 22 with its rear corner 23 round, this form of finger being strong, and being also constructed to make its swinging or turning entrance into the recess 13 easy, and when the inclined face 24: of the finger is forced against the under cut wall lk of the recess 13, the shoe and the plate are firmly locked together.

As a further modification, I show in Figs. 3 and 4% supplemental calks 25, which are arranged on the side opposite to the groove, or are arranged at the point where the bend is in the distorted plate When the plate is bent, as shown in Fig. 3, these supplemental calks being separated, as shown in the dotted outline, but when the plate is forced from its distorted position into its normal working shape, the supplemental calks 25 abut, as shown in Fig. i, and thesecalks, besides giving side support to the horses hoof, form additional means for preventing the dislodgement or removal of the plate from the shoe, since the tendency of the wear against the supplemental calks 25 is to constantly force the plate to its locking position.

It will be evident from this description that a horseshoe has a long life, since it can be fitted over and over again with the bottom plates which take up the wear, and are easilyattached by a driver, because the distorted plate, when laid against the shoe with 'it's fingers in the'rece ss'es, can be seated in nary tool, such as a screw driver, in the grooved part 16, and forcing the plate to its distorted position when it can be withdrawn again from the shoe, and if the plate is only partly worn it can be retained for further use.

Having now described my invention, I claim 1. The combination of a horseshoe with recesses therein, and a substantially flat plate to lie against the bottom face of the horseshoe, projections to enter the recesses of the horseshoe to hold the horseshoe and the plate together, the engaging portions of the recesses and projections being inclined, the plate having a narrow transverse recess on its top face to provide a thinned portion which, when worn through, separates the plate into two pieces.

2. The combination of a horseshoe having a recess in its front end and a recess near its back end, and a plate having separated proj ections to enter the recesses in the shoe, the plate being substantially of the same shape as the side of the horseshoe, the engaging faces of the projections and the recesses being inclined so that the projections hold the plate in place, the plate between the projections resting against the bottom face of the s cc.

3. The combination of a horseshoe having separated inclined recesses, and a plate to rest against the shoe and extending beyond said recesses, the plate having separated in clined projections entering the recesses of the shoe, the ends of the plate being turned away from the shoe to form calks, the major portion of the plate resting against the face of theshoe.

In testimony that I claim the foregoing, I have hereto set my hand, this 9th day of January, 1914:.

FERDINAND E. KAUFFMANN.
